Feeling useless spending the whole day writing?

I live with my parents and siblings. We recently hired a house keeper who cleans the while house so by the time the family wakes up in the morning, all house chores are done. There really is not kuch to do to help around except that my mom cooks our meals most of the time because she cant stand doing nothing. But while the rest of the family are watching series or going to the mall, i am at my computer all day either reading, watching lectures on creative writing, or writing. And i feel utterly useless as I do. It feels like i am wasting my time being boxed in my room all day. But when i check what the others are doing, they too were just entertaining thenselvesnout of boredom. But even that does not stop me from being feeling useless and a failure.

Any of you share my thoughts and experience?
